At this time, the second condenser 34 is not operated, as shown by the dotted line portion in fig. 3. The compressor 31 compresses the refrigerant into a high-temperature high-pressure saturated gaseous refrigerant, and the high-temperature high-pressure saturated gaseous refrigerant enters the first condenser 33 through the three-way valve 32 to perform heat dissipation and temperature reduction to form a low-temperature high-pressure liquid refrigerant, and the low-temperature high-pressure liquid refrigerant flows into the throttling device to form a low-temperature low-pressure liquid refrigerant. The low-temperature low-pressure liquid refrigerant exchanges heat with the gas in the gas guide passage 12 in the evaporator 37, is converted into a low-pressure high-temperature gaseous refrigerant, and then flows back to the compressor 31.
